This would assert if a constant address space was extern
and therefore didn't have an initializer. If the initializer
was undef, it would hit the unreachable unhandled initializer case.
An extern global should never really occur since we don't have
machine linking, but bugpoint likes to remove initializers.

RegisterSets are assumed to be terminated by this value. Loops over
register set values would fail without LLDB_INVALID_REGNUM terminating
the list. This change adjusts the static check to account for the
size of the register set regnum list being one larger than the expected
valid register set count.
llvm-svn: 210964
The llgs branch had a bug where register sets were not terminated with
LLDB_INVALID_REGNUM so the expedite register loop was issuing duplicate
registers. This test was added to catch the problem.
Enhanced the key-val collection method to optionally (and by default)
support capturing duplicate values for a given key. When that happens
and if permitted, it promotes a single key to a list and appends values
to it.

Now that we handle finding abstract variables at the end of the module,
remove the upfront handling and just ensure the abstract variable is
built when necessary.
In theory we could have a split implementation, where inlined variables
are immediately constructed referencing the abstract definition, and
concrete variables are delayed - but let's go with one solution for now
unless there's a reason not to.

Fixes a crash in Retain Count checker error reporting logic by handing
the allocation statement retrieval from a BlockEdge program point.
Also added a simple CFG dump routine for debugging.

I've been making some subtle changes to the gdb-remote tests as I implement
them in the llgs branch. This check-in rectifies the set of diffs that
have accumulated in the llgs branch that were not present upstream.

This patch is to move GlobalMerge pass from Transform/Scalar
to CodeGen, because GlobalMerge depends on TargetMachine.
In the mean time, the macro INITIALIZE_TM_PASS is also moved
to CodeGen/Passes.h. With this fix we can avoid making
libScalarOpts depend on libCodeGen.

Rather than relying on abstract variables looked up at the time the
concrete variable is created, look them up at the end of the module to
ensure they're referenced even if they're created after the concrete
definition. This completes/matches the work done in r209677 to handle
this for the subprograms themselves.
llvm-svn: 210946
This doesn't fix the abstract variable handling yet, but it introduces a
similar delay mechanism as was added for subprograms, causing
DW_AT_location to be reordered to the beginning of the attribute list
for local variables, and fixes all the test fallout for that.
A subsequent commit will remove the abstract variable handling in
DbgVariable and just do the abstract variable lookup at module end to
ensure that abstract variables introduced after their concrete
counterparts are appropriately referenced by the concrete variable.
llvm-svn: 210943
In an effort to fix concrete variables referencing abstract origins
where the concrete variable preceeds the first inlined usage, the
addition of attributes such as name, file, etc will be delayed until the
end of the module (to wait to see if any inlined instances have
occurred, thus necessitating an abstract definition that the concrete
definition should also reference).
These test cases don't actually need to care about this ordering of
attributes, so update them to be more resilient to such changes coming
in the near future.

This silently broke a long time ago when I unified some aspects of the
debug info schema. I'm just cleaning these up if/when they become a
problem.

Prior to this change, error handling functions must be installed
and removed only inside of an llvm_[start/stop]_multithreading
pair. This change allows error handling functions to be installed
any time, and from any thread.

Most builtins date from before the "cmpxchg weak" was a gleam in the
C++ committee's eye, so fortunately not much needs to change. But a
few of them *do* acknowledge that failure is possible.
For these, we'll emit the usual cartesian product of cmpxchg
operations if we can't statically determine weakness. CodeGen can
sort it out later if the function gets inlined.
The only other non-trivial aspect of this is (I think) that we emit
the scalar expression for "IsWeak" once, at the beginning, and
propagate its value through the successive blocks. There's not much in
it, but it's slightly more consistent with the existing handling of
FailureOrder.

Expedited registers currently checked for are pc, fp and sp.
Also broke out the gdb-remote base test case logic into
class gdbremote_testcase.GdbRemoteTestCaseBase in the new
gdbremote_testcase.py file.
TestGdbRemoteExpeditedRegisters.py is the first gdb-remote area
to be contained in its own test case class file.
The monolithic TestLldbGdbServer.py has been modified to derive
from gdbremote_testcase.GdbRemoteTestCaseBase. Soon I will
pull out all the gdb-remote functional area tests from that class
into separate classes.
I'm intending to start all GdbRemote test cases with GdbRemote
so it is easy to run them all with a -p pattern match on the
test run infrastructure.
Also scanned and removed all cases of whitespace-only lines in
the files I touched.

There are several Altivec tests that formerly ran only on big-endian
targets (and in some cases only on 32-bit targets). It is useful to
verify these on little-endian targets as well.
While testing these, I discovered a typo in <altivec.h>. This is also
fixed by this patch.
